Acne vulgaris ( Common acne) And Cystic Acne
Acne is a very common skin disorder that most young people get in early puberty. It is caused by inflammation of the small oil glands (sebaceous glands) that surround the fine hairs on the face and chest.
Acne is an inflammation of the pilosebaceous units of certain body areas (face and trunk, rarely buttocks) that occurs most frequently in adolescence and manifests itself as comedones (comedonal acne), papulopustules (papulopustular acne), or nodules plus cysts (nodulocystic acne and acne conglobata). Pitted, depressed, or hypertrophic scars may follow all types but especially nodulocystic acne and acne conglobata. Severe acne includes one or more of the following: persistent or recurrent inflammatory nodules, extensive papulopustular lesions, active scarring, and/or presence of sinus tracts.
More than four out of five people between the ages of 12 and 24 develop acne at least once. While the disorder is often associated with teenagers, it can affect people of all ages. It's not uncommon for acne to occur in people in their 20s and 30s. And, some people continue to have acne in their 40s and 50s. Some adult women experience mild to moderate acne due to hormonal changes associated with pregnancy, their menstrual cycles, or starting or stopping birth control pills.
Acne is rarely a serious medical condition, but it often causes emotional distress and can lead to scarring of the skin. With the right treatment, you can often keep acne under control. Measures also can be taken to reduce scars left by acne.
Why Do So Many Kids Get Acne?
A lot of kids and teens get a type of acne called acne vulgaris. It usually appears on the face, neck, shoulders, upper back, and chest. Teens and kids get acne because of the hormone changes that come with puberty. As you grow up and your body begins to develop, these hormones stimulate the sebaceous glands to make more sebum, and the glands can become overactive. When there is too much sebum, that oil clogs the pores and leads to acne.
No matter what you've heard, acne isn't caused by eating greasy foods like french fries or pizza, munching on chocolate, or drinking soda. It isn't necessarily caused by wearing makeup, either, especially if the makeup label says "oil-free," "noncomedogenic" (say: non- ka -mee-doh- jen-ick, which means it won't clog pores), or "nonacnegenic" (which means it doesn't cause acne).
